IMPROVEMENT IN HORSESHOE-MACHINES.

Specification forming part of Letters Patent No. EU-,GL dated November 721i, 1F63.

To @ZZ whom, t may concern,.-

Be it known that I, Moonn HARDAwQ-W, ofl

the city and county of St. Louis, and State of Missouri, have invented a new and useful lmprovement in Machines for Bending or Forming Horseshoes; and l do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon and made to form a part of this specification.

This invention relates, iirst, to the employment of horseshoe-forms, in combination with a rotating disk; second, in combination with said forms and disk, the use of certain clamps, and, third, to a device for releasing the formed shoes, all being constructed and arranged to operate substantially as hereinafter set forth, specied, and represented.

In reference to the accompanying drawings,

Figure 1 is a perspective view of my improve-- inent. Fig. 2 is a plan or top view. Fig. 3 is a sectional front elevation, and Fig. 4 is a sectional view of the disk and device for releasing the formed shoes.

A represents the platform or bed of themachine, which may be supported by suitable posts, A', and the said posts may be strengthcned by means of braces B B.

@represents the rotating disk, which will be formed of suitable material, metal being preferred, and may be sustained so as to rotate in proper position by means of a suitable arbor having bearings in supports eZ d of the bed A. The said disk may be provided with a driving cog-wheel, D, by .means of which the same may be operated.

j' represents the y forms around which the blanks will be bent. Said forms will be of suitable metal, and will be secured at equal distances upon the front face of the disk C, as clearly represented in Fig. 3, in such manner that they may be detachable, so that, if desired, different forms varying in size, in such manner as to be adapted to the different sizes of shoes required, may be employed. In the machine here represented, four of the said lforms are used, so that the machine is capable of forming four shoes during each revolution of disk C; but a greater or less number of said forms may be employed, the other working parts of the machine being constructed and arranged with reference to the number of forms to be used. The peculiar configuration ofthe said forms j' will, as nearly as possible, be that of the most perfect known form for horseshoes.

f/ f/ represent the clamps, arranged in duplicate upon the bed C, their rear ends heilig hinged or pivoted, as clearly shown in Figs. l. and 2, in such ina-nner as to allow lateral motion to their forward ends, which are pro- Avidedvwith the foriners c c. rFliese forrners extend forward so as nearly to touch the face ofthe disk C, and are formed with projecting shoulders, so constructed and arranged that suitable spaces may be afforded between the said shoulders and the face of the disk to receive the blanks which are to be formed. The said shoulders are adapted to hold the blanks in proper position while they are being forced between the formers by the forms f.

' 7L h represent cams, which are firmly sccured to the clamps g gf.

ri lZ represent bars firm-ly secured to sta-nd vided with friction-rollers k Zt.

Z Z represent bars arranged upon the braces B in such manner as to be prevented from lateral motion and allowed horizontal motion. The said bars ZZ are provided with frictionstandards j j.

n represents cams arranged upon and secured to the rear face of disk C in such inanner as to be adapted to come in contact with the friction-rollers m m at proper periods actuating the said bars ZZ and standards j j, so as to cause the bars Z fi to move forward, thereby forcing the rollers k Ztto bear against the cams 71y h of `the clamps g g', thereby compressing or contracting said clamps in such manner that the formers c e' will necessarily force theblanks into the configuration of th-e fornisf. The said bars Z Z, standards j j', bars t' i', and rollers 7.: Zt will be retracted by means of suitable springs. The said bars ZZ :may be desired, thereby dispensing with the standardsjj.

y) p represent brackets, which are adapted tion for operation.

s represents the rcleasers, which are adapted to remove the bent shoes from the forms. They ardsjj, (seen distinctly in Fig. 8,) and prorollers m m, and are rigidly secured to the in the operation ot' the machine, thereby arranged upon the top or face of the bed A, if

to confine the clamps g g/ in their proper posi-V are provided with pins s', which are made to pass through the disk to its front face, vand also with springs s, (seen in Fig. 4,) which are adapted to prevent the said pins from proj ecting out beyond the face of the disk, except at certain periods in the revolution of said disk, when the releasers s are made to pass under projections t t', above and below the bed A, by`

means of which the said springs will be compressed, and the pins s forced out against the formed shoes in such manner as to release them from the formsf and the disk C.

Having thus described the construction of my improvement, I will explain briefly its operation.

The working parts of the machine being nearly in the position shown in Figs. l and 2, and the disk being made to rotate in the direction of the arrows, blanks, heated in a suitable manner, may be fed to the machine upon cach side at the saine time.L Upon the right hand side, (looking toward the front face of the disk 0,) the blank will be fed above the formers, and upon the left-hand side below the l'ormers. As the disk C continues to rotate,tl1e

said'blanks will be carried upon the forms j', between the formers ee ofthe clamps g g', before described, and there bent into the proper form by the compressing action of the said clamps, through the medium of cams 7L h, rollers k c, bars t' t', standards jj, barsll, and

thus formed uponl the rightvhand of the machine will be removed from its form by means of a releaser, s, passing under alle projection f, and the shoe formed upon the left of the machine will in like manner be released by means of the projection t. When the said clamps have. been released by the retraction of bars Z Z', they will be expanded, so as to be ready to operate again, by means of springs m x.

Should it be found necessary, suitable rollers may be arranged in such manner that the forms f, together with the formed shoes, may pass under them, in order to remove any kinks or-wrinkles that may arise at the toes of the shoes during the process of bending.

Having `thus described my improvement,

what I claim as new and of my own invenh ereunto set my hand and seal, this 25th day of September,.l863, in presence of witnesses.
